I dunno, wifi just seems more useful to me than gps. I guess it depends on what you use it for though. I'm still not sold on navigation, I'm still in the stone ages with my atlas. I've got one of those 3" thick spiral bound ones in my vehicle all the time. It's come in very useful, not to mention that a map won't tell you to take the wrong turn because it needs a software update.
We were using a navigation unit over the summer and the thing got us lost on 20 miles of gravel road in the country in Kentucky. We were going to the maker's mark distillery in Loretto by the side roads and had it not been for the atlas we'd have never made it there. The navigation unit told us to drive down an old creek bed.
